What is the title of the Arthur episode about breast cancer?

The Arthur episode about breast cancer is titled “The Great MacGrady.”

The episode centers on Mrs. MacGrady, Lakewood Elementary’s beloved lunch lady, after she takes leave because she has cancer. Arthur, D.W., Muffy, Francine, and their classmates respond in different ways, showing that fear, sadness, awkwardness, and uncertainty are all understandable reactions to serious illness.

“The Great MacGrady” originally aired during Arthur’s 13th season on October 19, 2009. Lance Armstrong appeared as himself and spoke with Francine about surviving cancer, inspiring her to organize a “Pedal for a Cure” benefit bike race. The story also emphasizes practical support, such as helping with chores rather than simply bringing gifts.

The episode was later revised for Season 24 after Armstrong’s doping scandal. His role was replaced by the fictional wrestler Uncle Slam, but the title and central cancer storyline remained. That revision can cause confusion about whether there are two similarly titled episodes; they are different versions of the same story.
